SIGNAL BELL.

Application led August 15, 1922. Serial No. 581,936.

j'o ali whom t may concern: Y

Be it known that I, SAMUEL C. Ronnss, a citizen of the United States, and resident of New York, in the county of New York and State of New York, havevinvented certain new and useful Improvements in Signal Bells, of which the following is a specification.

In my applications for improvementsin 1o signal bells, iiled November 30th, 1921, Serial #541,236and iiled May 12th, 1922, Serial #560,284, I have disclosed means for operating the clappers of signal bells by means of the pressure of gases from an inw ternalcomb-ustion engine.

The object of my present invention is to provide simplified and effective means for operating the clapper in the class of signal bells referred-to whereby the clapper will 2o be rocked during each reciprocation ofthe movable member or piston that is actuated by the ases and whereby the parts will not be liable to injury or deterioration through undue wear.

,My invention comprises novel details of A improvement that will be more Jrully hereinafter set forth and then pointed out in the claims.- Y

v Reference is to be had totheacc-ompany- Fig. 1 is a vertical section of a signal'V bell embodying my invention;

Fig. 2 is a section onI line 2,2 in 'Fig'.v

1, showing parts in a lowered position;

Fig. 3 is a partlysectional detail view; Fig. 4 is a section on line 4, 4 in Fig. 1,

and

Fig. 5 is a diagrammatic view illustrating my .improvements upon a portion of an 4o automobile.

Similar numerals of reference indicate corresponding parts in the several views.

At 1 is indicated a bell which may be of. any suitable construction, and at 2 is indicated a tubular support to which the bell is vattached by a threaded piece or screw 3, or in any other suitable manner. A movable member or piston 4 is adapted vto reciprocate within bore 2a of support- 2 to operate a clapper 5 that is ,adapted to strike the bell. The clapper 5 is shown pivotally, supported at its upper lend upon a laterally disposed lug 6 extending Jfrom Support 2 receiving pivot 7 for the clapper. Below lug 6 the support 2 is provided with slots or openings 8, 9 disposed on opposite sides of and communicating with bore 2a. A link 10 is pivotally connected with the clapper by pivot 11, which link is shown disposed within a slot 5a in the clapper. and said link at its inner end extends within bore 2a and is pivotally connected with the member 4, by means of a rocker arm 12, within bore 2a, pivotally connected by means of pivot 13 with link 1() and pivotally connected with member 4 by means of pivot14.

One or more links l5 are pivotally connected with pivot 13 and are also pivotally connected with support 2 by means of pivot or screw 16 that is carried by lugs 17 eX- tending from support 2. By preference I use one link 10 and two spaced links 15 between which the inner portion of link 10 operates, (see Fig. 4). The pivots 7, 11 and 16 may be in the form of screws provided with nuts to retain them in position. The length of the links, the position of the pivot of clapper 5, and the point of pivotal connection of. the links with bar 12 are such that when member 4 is in its upper or its lower position, the links on opposite sides ofthe common pivot 13 will be at an angle with respect. to each other, whereby the clapper will be drawn or held away from the bell, and when the member 4 is in an intermediate position the links will be substantially in a straight line, as indicated in Fig. 1 to cause the outward movement of the clapper whereby the latter will strike the bell. During the reciprocations of member 4 the bar 12 will have lateral motion to accommodate for the rocking of links 15, since the pivot 18 follows an are de scribed around the axis of pivot 16.

Since the clapper is rocked or 'oscillated by mea-ns of the reciprocating movements of member 4 I desire to limit the upward and downward movements of member 4,

- per will cease and this will cause longitudinal movement of member 4 to cease in either direction of its motion without requiring said member to engage any positive stop Y upport 2may be attached to any desired party for supporting the bell in convenient position for use. I have shown the lower end of support 2 threaded to. receive cor responding threads 19 at the upper end. of a fitting 20, the lower end ot which fitting mayv be attached to a retaining plate 21 shown provided -wit-li internal threads 22 receiving theI threaded part 23 of fitting 20. The retaining plate is shown provided with a recess 24 on its'iinder side adapted to receive a. fitting 25 to connect the parts to a pipe 26. The support 2 er the fitting 2O may be attached toy an automobile, boat or the like in any other desired way.

In Fig. 5 I have shown means to control pressure and exhaust through pipe 26, coinprising a valve construction substantially similar to the construction shown in my application, ,Serial #260,284 aforesaid. The valve casing 27 may be secuie-d to a cylinder of an internal combustion engine, indicated at 28, a lever 29 being adapted to operate a valve that will control the flow of gas to orfrom the engine through the pipe 26. rIhe lever 29 may be operated by means ofa connection 31 extending to any dcsired manually operated device which may besupported upon the dashboard oit an automobile or in any other c onvenient position. In Fig. 5 the retaining plate 21 is.

shown attached upon a bracket 32 secured upon the cowl of an automobile.

In order to opei'ate the bell the pipe 26 isplaced in communication with a source of'pressure and exhaust, such as in connection with an internal combustion engine cylinder, and when the valve controlling pipe 26 is opened the pressure from the cylinder will push member 4 outwardly in bore or cylinder 2a, whereby the operation ot the links beforedescribed will cause the clapper to move outwardly to strike the bell and when such pressure is released and exhaust occurs in pipe 26 member 4 will descend to cause corresponding outward movement of the clapper to. strike the bell, the clapper being drawn away from the bell after ineinber 4 has moved the links on opposite sides of a straight line through the links. The reciprocations of the member 4 may be quite rapid so that the clapper may be operated with rapidity to ring the bell.

The actuator for the clapper, comprising the links described that .arev pivoted to the support 2 and to the clapper, operates in the nature ot toggles, actuated in opposite directions by the reciproc-ative member or piston 4, whereby a smooth action of the clapper is'eected. The moment of contact of the clapper and the bell may be controlled by a headed screw 5a carried by the clapper and retained by a nut 5b, since said screw can be set for line adjustment respecting the bell when the links are in a straight line.

I-Iaving now described my invention what I claim is 1. A signal bell comprising a support, a bell, a clapper, a movable member, means to operate the member by uid pressure and exhaust, andopposing links pivotally connected with a movable part that is pivotally connected with the member, one of said links being Vpivotally. connected with the support and the other link being pivotally connected with the clapper.

2. A signal bell comprising a support, a bell, a clapper, a movable member, means to operate the member by fluid pressure and exhaust, and links pivotally connected at adjacent ends with a movable part that is pivotally connected with said member, one of said links beingv pivotally connected at its opposite end with the clapper and another of said links vpivotaliy,connected at its opposite end with said support.l

3. A signal bell comprising a support, a bell, a clapper, a movable member, means to operate the member by fluid pressure and exhaust. and links respectively pivotally connected at.y their outer-ends with the clapper and the support, and a bar pivot-ally connected with said member and with adjacent inner en ds'of said links.
